Carbon dioxide is the main greenhouse gas responsible for global warming. It is released from burning fossil fuels, industrial processes, and deforestation. Its increasing level in the atmosphere traps heat and raises Earth’s temperature.
Climate change has become one of the most discussed global issues in recent years. Rising temperatures, melting glaciers, and extreme weather events are direct effects of increased carbon dioxide levels.
